1. SCOPE
|
|
|
|
This document provides a general design overview of the Server Manager
|
|
User Sub-Property Sheet implementation. It describes the class
|
|
declarations, the flow of information, and the general algorithms used.

3. OVERVIEW
|
|
|
|
The Server Manager Users Sub-Property Sheet (USPS) is the dialog that
|
|
allows for administration of user sessions. The USPS allows the user to
|
|
see the current user sessions, and to selectively disconnect either the
|
|
user or resource that they are connected to.
|
|
<<< WARNING: This is how it is spec'ed BUT since only one session is
|
|
established for a connection between machines, it is impossible
|
|
to disconnect only one resource. It is all or nothing. >>>
|
|
|
|
4. CLASS OVERVIEW
|
|
|
|
The USER_PROPERTIES class implements the USPS dialog. It contains code
|
|
for processing the sessions to a given machine and then tracking those
|
|
resources to see what the real name of the resource is.
|
|
|
|
|
|
5. CLASS DETAILS
|
|
|
|
This section details the interfaces to the above described classes.
|
|
Note that only the public: and protected: sections of the class
|
|
declarations are given.
|
|
|
|
5.1 USER_PROPERTIES
|
|
|
|
The USER_PROPERTIES class is declared as follows:
|
|
|
|
class USER_PROPERTIES : public DIALOG_WINDOW
|
|
{
|
|
protected:
|
|
BOOL OnCommand( CID cid, ULONG lParam );
|
|
|
|
BOOL OnOK( VOID );
|
|
|
|
public:
|
|
USER_PROPERTIES( HWND hWndOwner,
|
|
SERVER_2 * psrv2 );
|
|
|
|
~USER_PROPERTIES();
|
|
|
|
}; // class USER_PROPERTIES
|
|
|
|
Note: There are current plans to subclass DIALOG_WINDOW
|
|
(or VALIDATED_WINDOW) into PROPERTY_WINDOW and
|
|
SUBPROPERTY_WINDOW. USER_PROPERTIES will inherit from
|
|
SUBPROPERTY_WINDOW when this class becomes available.
|
|
|
|
The OnCommand() method is responsible for handling all action
|
|
items from the Disconnect buttons, and the auto disconnect
|
|
magic value control.
|
|
|
|
OnOK() is responsible for updating the information at the server,
|
|
specifically the auto disconnect interval.
|
|
|
|
Note: There will be a Refresh() method provided when
|
|
the design for dialog refresh is stable.
|
|
|
|
6. OPERATION
|
|
|
|
The USER_PROPERTIES class performs the following operations:
|
|
|
|
Get the name of the server from the SERVER_2 object. Then do a
|
|
NetSessionEnum( Level 1 ) to get the list of users connected to
|
|
the server this information will also be used to the number of
|
|
connected users field in the dialog. The list of users will then
|
|
be matched against calls to the following API's to generate a list
|
|
of the current resources that the user is connected to.
|
|
|
|
NetFileEnum2() - Open Files, File Locks,
|
|
Open Named Pipes
|
|
NetCharDevQEnum() - Open Comm Ports
|
|
DosPrintQEnum() - Print Jobs
|
|
|
|
|
|
Note: What about share level servers? The current
|
|
Server Manager Functional Specification does not address
|
|
share level servers.
|
|
|
|
7. OPEN ISSUES
|
|
|
|
How do we selectively nuke resources?
|
|
A better question would be: How are we going to compensate for this
|
|
functionality
|
|
|
|
